2.23. Hydraulic pushers of valves

GENERAL INFORMATION

On engines with big term of operation probably pollution got in the hydraulic valve therefore it is recommended to assort and clear each time when dismantling a head of the block of cylinders hydraulic pushers. Spare parts to hydraulic pushers do not go on sale, therefore at failure of any detail of a pusher it is necessary to replace a hydraulic pusher assembled.

Details of a hydraulic pusher

1–bearing;
2–plunzher;
3–ball;
4–small spring;
5–cover;
6–big spring;
7–cylinder


Installation of a ball (1) in a nest (2) in the basis of a plunzher

Arrangement of a small spring (1) in a cover and a ball (2) in a nest of a plunzher

Screw-driver use for cover installation in a flute of a plunzher

Installation of a big spring on a cover of a plunzher

Installation of a plunzher with a spring in the cylinder of a hydraulic pusher

Bearing installation
At bearing (1) installation it should be fixed accurately in a flute of the cylinder of a pusher (2).

PERFORMANCE ORDER
1. After dismantling of a head of the block of cylinders check a condition of nests of pushers in a head. If nests of pushers are worn-out, replace a head of the block of cylinders. Also check a condition of openings in a head of the block of cylinders for supply of oil to hydraulic pushers.
2. Consistently, since a pusher of the valve of the first cylinder, being careful, remove the bearing from the top part of the cylinder of a hydraulic pusher. Take from the cylinder of a hydraulic pusher a plunzher and a spring.
3. An edge of a small screw-driver, being careful, uncover the basis of a plunzher and take a spring and a ball.
4. Clear details of a hydraulic pusher kerosene or solvent and wipe or dry up pusher details. Check a condition of springs and in the presence of damages or deformation replace a hydraulic pusher assembled.
5. Grease details of a hydraulic pusher with pure engine oil and collect a pusher.
6. Overturn a plunzher and insert a ball into an opening in the basis of a plunzher (see fig. Ball installation in a nest in the basis of a plunzher).
7. Establish a small spring in a cover of a plunzher, then, being careful, establish a cover with a spring. Check that the spring draws in a ball. Using a screw-driver edge, press a cover into a flute of a plunzher (see fig. An arrangement of a small spring (1) in a cover and a ball (2) in a nest of a plunzher, screw-driver Use for cover installation in a flute of a plunzher).
8. Establish a big spring on a cover of a plunzher (see fig. Installation of a big spring on a cover of a plunzher).
9. Insert a plunzher with a spring into the pusher cylinder (see fig. Installation of a plunzher with a spring in the cylinder of a hydraulic pusher).
10. Establish the bearing on the top part of a plunzher and, being careful, hands compress a plunzher before accurate fixing of the bearing in a flute of the cylinder of a pusher (see fig. Bearing installation).
